What defines an invasive plant?

An invasive plant is defined as a non-native species that, when introduced to a new environment, causes harm to the local ecosystem, economy, or human health. This can include aggressive growth that outcompetes native plants for resources such as sunlight, space, and nutrients, which ultimately disrupts local biodiversity. The classification of a plant as invasive is often based on its ability to spread rapidly and establish in a wide range of habitats, leading to negative consequences for native flora and fauna.

The other options do not accurately describe what makes a plant invasive. A plant originating from the local area is by definition native and does not pose the same risks. Plants with beneficial uses can be non-invasive or even beneficial to their ecosystems. Additionally, some invasive plants may thrive in various environments, not just wetlands, so a focus on growth in wetland areas does not encompass the broader impact of an invasive species.
